Trichopezizella relicina (?) - on wood!
Lothar Krieglsteiner, 05-08-2024 08:26
Lothar KrieglsteinerFrench Alps, 13.7.24, on twig of either Alnus alnobetula or Salix below a mixed shrub above road side. I think a lot is fitting for T. relicina: the rb-ascus-apex, the "ornamented" paraphyses, the very long and macroscopically teeth-like agglutinated hairs, etc. I noted asci with croziers but have no foto of this.
The spores I measured a bit small, only about 10-13/2-2,3, but this could still fit. Has somebody else found T. relicina on wood?
Best regards, Lothar

Re : Trichopezizella relicina (?) - on wood!
My literature database gives a lot of different herbaceous plants but also one case of wood: Sambucus racemosa (Haines 1974: 234). My personal studies include only herbs.

I recommend to verify the host genus ba a radial section of the wood (ladder-perforations in Alnus vs. simple perforations in Salix). Also a cross-cut would distinguish the two.

Breitenbach & Kränzlin also give only spores of 8-12 µm

Hello Zotto,
thank you for your reply.
I will by time do the wood-anatomy. Will take some time, I will write again.
Best regards, Lothar

Re : Trichopezizella relicina (?) - on wood!
now I made section through the crumbly wood. I think it should be Alnus then?
(1st foto: cross section, 2nd and 3rd foto: radial section). 
Yours, Lothar

Hallo Lothar

impossible for Alnus. Could be Acer but the radial sections I cannot interpret, one needs a hit through such a vessel as we see in the cross section.

Re : Trichopezizella relicina (?) - on wood!
thanks.
Acer does not grow in the vicinity.
Everything but Alnus and Salix is very unlikely.
I will try again later.

Salix and Populus could be possible.

Re : Trichopezizella relicina (?) - on wood!
then it must be Salix.
As I already posted in the first contribution, there was a bush of Alnus alnobetula and Salix above the findplace. Other trees and bushes grew only far away (Picea, Rhododendron). 
Then Salix.
Thanks again, Lothar
